Scientists make world's smallest animation with atoms

Scientists make world's smallest animation with atoms | Social Foraging | Scoop.it

Researchers used a scanning tunnelling microscope to move thousands of carbon monoxide molecules to make an animated short film depicting a stick boy playing with his pet atom.

 

In the one-minute video, individual molecules are repeatedly rearranged to show a boy dancing, throwing a ball and bouncing on a trampoline.

 

The film, called A Boy and His Atom, is so small it can be seen only when magnified 100 million times.

 

The ability to move single atoms — the smallest particles of any element in the universe — is crucial to IBM's research in the field of atomic memory.

 

The company has honed atomic-manipulation technique after years of researching atomic data storage.

The physics of terror - Revealing the rhythms and patterns of violence

The physics of terror - Revealing the rhythms and patterns of violence | Social Foraging | Scoop.it

Statisticians are borrowing models from seismology and physics to forecast future patterns of war and terrorism

 

What is the risk of a war on the Korean peninsula or South China Sea? Or, for that matter, of another terrorist attack on American soil? These are questions that western diplomats and security experts are asking themselves this spring. And as speculation grows, those officials have been duly scouring satellite feeds, intelligence reports and history books.

 

Over in Colorado, Aaron Clauset, a computational scientist, is pondering the dangers from a different perspective. Clauset, who teaches at the University of Colorado, Boulder and is part of the Santa Fe Institute, has spent the past decade on the frontier of computing and statistical research. But he has not focused on areas normally beloved by geeks, such as engineering, physics or biology.

MQTT Telemetry Transport: Is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol

MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. For example, it has been used in sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small device scenarios. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers

Asymptotic Behaviour and Ratios of Complexity in Cellular Automata

We study the asymptotic behaviour of symbolic computing systems, notably one-dimensional cellular automata (CA), in order to ascertain whether and at what rate the number of complex versus simple rules dominate the rule space for increasing neighbourhood range and number of symbols (or colours), and how different behaviour is distributed in the spaces of different cellular automata formalisms. Using two different measures, Shannon's block entropy and Kolmogorov complexity, the latter approximated by two different methods (lossless compressibility and block decomposition), we arrive at the same trend of larger complex behavioural fractions. We also advance a notion of asymptotic and limit behaviour for individual rules, both over initial conditions and runtimes, and we provide a formalisation of Wolfram's classification as a limit function in terms of Kolmogorov complexity.

Birdsong, Speech, and Language: Exploring the Evolution of Mind and Brain

Scholars have long been captivated by the parallels between birdsong and human speech and language. In this book, leading scholars draw on the latest research to explore what birdsong can tell us about the biology of human speech and language and the consequences for evolutionary biology. They examine the cognitive and neural similarities between birdsong learning and speech and language acquisition, considering vocal imitation, auditory learning, an early vocalization phase ("babbling"), the structural properties of birdsong and human language, and the striking similarities between the neural organization of learning and vocal production in birdsong and human speech. After outlining the basic issues involved in the study of both language and evolution, the contributors compare birdsong and language in terms of acquisition, recursion, and core structural properties, and then examine the neurobiology of song and speech, genomic factors, and the emergence and evolution of language.

Bit.ly is an URL shortener (like tinyurl.com), but it offers much more than redirect services (everybody can create a redirect service), thanks to its interesting reporting capabilities. They recently hired a famous data scientist, Hilary Mason, see picture below.

 

And this service it is an example of great big data - provided you are aware of their incredibly simple - yet incredibly powerful dashboard (I love simple dashboards). It is also a classical example of big data that is useless unless you are aware of the features coming with it, and how to leverage it. So here's what I found to be especially useful.

Robot Discovers 2,000-Year-Old Burial Chambers

Robot Discovers 2,000-Year-Old Burial Chambers | Social Foraging | Scoop.it

A small robot has uncovered three 2,000-year-old chambers under an ancient temple in Mexico, archaeologists from the National Anthropology and History Institute announced this week.

 

The robot, named Tlaloc II-TC after Mexico's ancient god of rain, found the chambers under the Temple of the Feathered Serpent (also called the Temple of Quetzalcoatl) in the Mesoamerican ruins of Teotihuacan, which is just 30 miles from Mexico City. The ancient city, thought to have been established around 100 BC, had more than 100,000 inhabitants at its peak, but had long been abandoned before the Aztecs arrived in the 1300s.

 

In the 1980s, the remains of over 200 warriors were found in the core of the Temple of the Serpent. Archaeologists found a tunnel under the same temple in 2011 using radar technology. They then deployed the remote-controlled robot, which is equipped with an infrared camera and a scanner that generates detailed maps of the chambers beneath the temple. Three feet long, it can squeeze into tight spaces where a person would otherwise be unable to explore.

Google Predicts Stock-Market Crashes, Study Suggests

Google Predicts Stock-Market Crashes, Study Suggests | Social Foraging | Scoop.it

On Tuesday (April 23), a tweet from a hacked Associated Press account claiming there had been explosions at the White House sent the Dow Jones Industrial Average plummeting 145 points almost instantaneously. The incident was an example of how quickly the Internet can send shock waves through the financial world, given how many trades are completed by computers rather than humans.

 

But new research finds the financial world doesn't just respond to the Internet; the Internet can also predict what the stock market will do. The research isn't the first to find such online clairvoyance. For example, Google may even be able to predict medication side effects before doctors can, thanks to people's tendencies to self-diagnose using the search engine. Google searches can also forecast the spread of the flu.

 

The new study, however, takes the extra step of testing out how well stock-buying would go, using Google search trends as guidance. The result: a pretty nice return.

The honey and the ivy – why gardeners’ foe is the bees’ friend

The honey and the ivy – why gardeners’ foe is the bees’ friend | Social Foraging | Scoop.it

The research, carried out by scientists at the Laboratory of Apiculture and Social Insects (LASI), is published online today (Friday 26 April) in the journal Insect Conservation and Diversity.

 

 

The researchers surveyed ivy flowers from rural and urban locations to count the honey bees and other insects foraging for nectar and pollen. They also identified the pollen brought back to hives by honey bee workers to determine the proportion from ivy and then surveyed ivy to determine how widespread it is.

 

 

In addition, the researchers measured the sugar concentration in nectar collected from ivy flowers by honey bee workers, and determined what proportion of honey bee foragers on ivy were collecting nectar versus pollen.

 

The data collected from hives on campus, from nearby Falmer village and from Brighton’s Dorothy Stringer School showed that, contrary to what might be expected, bee foraging distances decreased from summer to the autumn.

 

 

As ivy blooms mainly in September and October, this suggested that the plant was having a beneficial effect on bee foraging, resulting in the bees having to fly shorter distances to find high-quality flowers.

 

 

Having access to high-quality supplies of nectar and pollen late on in the flower season improves the chances of successful over-wintering for the hive.

Physicist Proposes New Way To Think About Intelligence: A radical concept could revise theories addressing cognitive behavior.

Physicist Proposes New Way To Think About Intelligence: A radical concept could revise theories addressing cognitive behavior. | Social Foraging | Scoop.it

A single equation grounded in basic physics principles could describe intelligence and stimulate new insights in fields as diverse as finance and robotics, according to new research.

 

Alexander Wissner-Gross, a physicist at Harvard University and the Massachusetts Institute of Technology, and Cameron Freer, a mathematician at the University of Hawaii at Manoa, developed an equation that they say describes many intelligent or cognitive behaviors, such as upright walking and tool use.

The researchers suggest that intelligent behavior stems from the impulse to seize control of future events in the environment. This is the exact opposite of the classic science-fiction scenario in which computers or robots become intelligent, then set their sights on taking over the world.

The findings describe a mathematical relationship that can "spontaneously induce remarkably sophisticated behaviors associated with the human 'cognitive niche,' including tool use and social cooperation, in simple physical systems," the researchers wrote in a paper published today in the journal Physical Review Letters.

"It's a provocative paper," said Simon DeDeo, a research fellow at the Santa Fe Institute, who studies biological and social systems. "It's not science as usual."

Wissner-Gross, a physicist, said the research was "very ambitious" and cited developments in multiple fields as the major inspirations.

The mathematics behind the research comes from the theory of how heat energy can do work and diffuse over time, called thermodynamics. One of the core concepts in physics is called entropy, which refers to the tendency of systems to evolve toward larger amounts of disorder. The second law of thermodynamics explains how in any isolated system, the amount of entropy tends to increase. A mirror can shatter into many pieces, but a collection of broken pieces will not reassemble into a mirror.

The new research proposes that entropy is directly connected to intelligent behavior.

The Internet of Things gets a protocol -- it's called MQTT

Setting the foundation for what may be a multitrillion-dollar marketplace, OASIS (the Organization for the Advancement of Structured Information Standards) has declared MQTT (the Message Queuing Telemetry Transport) as its messaging protocol of choice for the emerging Internet of Things.

 

"One of the big challenges for right now is that there is not a clear open standard" for message communication with embedded systems, said Mike Riegel, an IBM vice president of mobile and application integration middleware. "We know historically that unless you get to an open standard like this, it is not possible to drive the breakthroughs that are needed."

 

In much the same way that the HTTP standard paved the way for people sharing information through the World Wide Web, MQTT could set the stage for bringing online billions of low-cost, embedded data-collecting telemetry devices, Riegel said.

 

The Internet of Things is not a network, but a new marketing phrase that describes the growing use of network-connected embedded microprocessors, often connected to sensors or other data-gathering instruments. Because microprocessors are now so inexpensive and networks are so pervasive, such embedded systems could provide a wealth of data that organizations in most industries could use to monitor and improve operations.

Stephen Hawking’s advice for twenty-first century grads: Embrace complexity

 A few years ago, Hawking was asked what he thought of the common opinion that the twentieth century was that of biology and the twenty-first century would be that of physics. Hawking replied that in his opinion the twenty-first century would be the “century of complexity”. That remark probably holds more useful advice for contemporary students than they realize since it points to at least two skills which are going to be essential for new college grads in the age of complexity: statistics and data visualization.

Price: $19.15
You Save: $7.80 (29%)

The P-NP problem is the most important open problem in computer science, if not all of mathematics. The Golden Ticket provides a nontechnical introduction to P-NP, its rich history, and its algorithmic implications for everything we do with computers and beyond. In this informative and entertaining book, Lance Fortnow traces how the problem arose during the Cold War on both sides of the Iron Curtain, and gives examples of the problem from a variety of disciplines, including economics, physics, and biology. He explores problems that capture the full difficulty of the P-NP dilemma, from discovering the shortest route through all the rides at Disney World to finding large groups of friends on Facebook. But difficulty also has its advantages. Hard problems allow us to safely conduct electronic commerce and maintain privacy in our online lives.

IDEAL'13 – Special Session on Swarm Intelligence and Data Mining (SDIM 2013)

The 14th International Conference on Intelligent Data Engineering and Automated Learning (IDEAL'2013).

 

Swarm intelligence is a recent trend in computational intelligence and popular for the simplicity of its realizations, such as particle swarm optimization (PSO), ant colony optimization (ACO), bee colony optimization (BCO), and the like. As optimization techniques, methods in swarm intelligence have been applied to many aspects in the fields of data engineering and automated learning. For example, as reported in the literature, PSO has been adopted to handle data clustering, and ACO has been employed to solve the problem of classification.

 

On the other hand, advances in data mining, an important section in data engineering and automated learning, also assist optimization algorithm designers to develop better methods. For instance, Apriori algorithm has been utilized for finding the relationship among decision variables for optimizers. In order to bridge the concepts and methodologies from the two ends, this special session concentrates on the related topics of integrating and utilizing algorithms in swarm intelligence and data mining. It provides the opportunity for practitioners handling their data mining issues by using swarm intelligence methodologies and for researchers investigating swarm intelligence with data mining approaches to share findings and look into future directions.

The collateral damage of internet censorship by DNS injection

The collateral damage of internet censorship by DNS injection | Social Foraging | Scoop.it

Some ISPs and governments (most notably the Great Firewall of China) use DNS injection to block access to "unwanted" websites. The censorship tools inspect DNS queries near the ISP's boundary routers for sensitive domain keywords and inject forged DNS responses, blocking the users from accessing censored sites, such as twitter and facebook. Unfortunately this causes collateral damage, affecting communication beyond the censored networks when outside DNS traffic traverses censored links. In this paper, we analyze the causes of the collateral damages and measure the Internet to identify the injecting activities and their effect. We find 39 ASes in China injecting forged DNS replies. Furthermore, 26 of 43,000 measured open resolvers outside China, distributed in 109 countries, may suffer some collateral damage from these forged replies. Different from previous work that considers the collateral damage being limited to queries to root servers (F, I, J) located in China, we find that most collateral damage arises when the paths between resolvers and some TLD name servers transit through ISPs in China.

You Can Benefit from a Rival’s New Product - Harvard Business Review

When a company comes out with a new product, its competitors typically go on the defensive, doing whatever they can to reduce the odds that the offering will eat into their sales. Responses might include cranking up marketing efforts, offering discounts to channel partners, and even lobbying for regulations that would hinder the rival’s expansion. In many cases, though, such actions are misguided. Although the conventional wisdom that a rival’s launch will hurt profits is often correct, my research shows that companies sometimes see profits increase after a rival’s rollout—even when they don’t aggressively seek ways to squelch the new product’s sales.

 

The underlying mechanism is pretty simple: When a company extends a product line, it often raises the prices of its existing products. The hikes might be designed to make the new product look cheaper and thus more attractive by comparison or to capture the value customers place on a broader line of offerings. As that company adjusts its pricing, its competitors can follow suit without risking customer defections over price.

 

Consider what happened when Yoplait became the first major producer to market low-fat yogurt in the United States. Although Dannon took a 5% hit in units sold during the new product’s initial year, the vast majority of its customers didn’t defect to Yoplait; they preferred Dannon’s style of yogurt. And because Yoplait had raised prices across its product line, Dannon raised its prices as well, by more than 10%. So despite the 5% decrease in volume, Dannon’s revenue increased by 5%.

Computer scientists start second project to improve access to NHS patient database

Computer scientists start second project to improve access to NHS patient database | Social Foraging | Scoop.it

Two Sussex academics have begun work on developing a system for assessing the quality of patient information held in a new NHS database.

 

Dr Rosemary Tate, a medical statistician and computer scientist in Informatics, and Dr Natalia Beloff, Senior Lecturer in Software Engineering, worked with Brighton-based company Dataline Software to develop a system, called TRIALVIZ, that allows users to extract real-time information from the database and to search based on a specified set of criteria. Prior to this, extracting such information was time-consuming and required considerable expertise.
 
The current application of this tool will help in the development of new medicines, by enabling users to select suitable patients for a clinical trial. But the flexible design means that many other healthcare applications are possible.
 
Now, in a second project, Dr Tate has been awarded a one-year Senior Research Fellowship to develop a mechanism for assessing – and improving – the quality of the data held within the CPRD.
 
Working with Dr Beloff, Dr Tate will develop a protocol and framework for measuring data quality, and will also create a software component for extracting data-quality statistics and constructing practice-based quality scores.

An Introduction to Social Media for Scientists

An Introduction to Social Media for Scientists | Social Foraging | Scoop.it

In many ways, the fast-paced evolution of the internet parallels the move toward “big data” in science. In less than a decade, online tools have exploded in popularity and witnessed rapid expansion (Figure 1), with an increasing number of scientists now looking to take advantage of these web-based resources (see Box 1 and Table 1 for an overview and comparison of existing tools). Social media portals in particular undergo regular reinvention and transformation, with different tools becoming popular for different populations [1]. Although a number of guides exist online, many researchers still feel overwhelmed and hesitant toward the virtual world, lacking sufficient information and guidance through formal scientific channels such as peer-reviewed journals. To better familiarize researchers with existing internet resources, here we discuss prospective benefits that can stem from online science conversations, explain how scientists can efficiently and effectively harness online resources, and provide an overview of popular online tools.
